[0028] See also Figure 1-4 A dustproof structure of a sealing sleeve in this embodiment includes a sealing shell 1 and a wiring harness connecting portion 2, and a dustproof mechanism 3 is arranged in the sealing shell 1.

[0029] The sealing shell 1 includes a screw 4 threadedly installed on the inner circumferential wall of the sealing shell 1, a handle 5 is fixedly connected to the outer circumferential wall of the screw 4, a first dustproof plate 6 is fixedly connected to the screw 4, a limiting rod 7 is fixedly connected to the lower surface of the first dustproof plate 6, a first adjustment plate 8 is fixedly connected to the outer circumferential wall of the limiting rod 7, a second adjustment plate 9 is fixedly connected to the outer circumferential wall of the limiting rod 7, a clamping plate 10 is fixedly connected to the lower surface of the limiting rod 7, a second dustproof plate 11 is fixedly connected to the inner circumferential wall of the sealing shell 1, a clamping groove 12 is opened in the second dustproof plate 11, a spring 13 is fixedly connected to the inner circumferential wall of the clamping groove 12, a first limiting plate 14 is fixedly connected to the outer circumferential wall of the spring 13, and a second limiting plate 15 is fixedly connected to the lower surface of the first limiting plate 14.

[0030] In this embodiment, the handle 5 is located outside the sealing shell 1. In order to facilitate the user to connect the wiring harness through the first dustproof plate 6 and the second dustproof plate 11, the user can pull the handle 5 to drive the screw 4 to rotate. There are two springs 13. By increasing the number of springs 13, the fixing effect can be increased.

[0031] In this embodiment, the two springs 13 are respectively located at the left and right ends of the card slot 12, and the first adjustment plate 8 is located at the lower end of the second adjustment plate 9, so that the first adjustment plate 8 and the second adjustment plate 9 can push the first limit plate 14 respectively, thereby driving the second limit plate 15 to move laterally, so that the card plate 10 can be limited by the lateral movement of the second limit plate 15.

[0032] In this embodiment, the length of the first adjustment plate 8 is smaller than that of the second adjustment plate 9. In order to enable the first adjustment plate 8 and the second adjustment plate 9 to have different lengths, the first limit plate 14 and the second limit plate 15 can be pushed to move different distances, thereby controlling the limit of the card plate 10. The first dustproof plate 6 and the second dustproof plate 11 are both arc-shaped plates.

[0033] In this embodiment, the first dustproof plate 6 and the second dustproof plate 11 are adapted to each other.

[0035] The working principle of the above embodiment is:

[0036] After the user's wiring harness passes through the sealing shell 1 and the wiring harness connecting part 2, the user drives the screw 4 to rotate by turning the handle 5 clockwise, and the screw 4 drives the first dustproof plate 6 to move downward, and the first dustproof plate 6 moves downward, and the first dustproof plate 6 enters the slot 12. The first adjustment plate 8 on the outer peripheral wall of the first dustproof plate 6 pushes the first limit plate 14 to move in the direction of the spring 13, and the first limit plate 14 drives the second limit plate 15 to move in the direction of the spring 13. When the first adjustment plate 8 continues to move downward until the first adjustment plate 8 After the section plate 8 stops pushing the first limit plate 14, the card plate 10 is located at the lower end of the second limit plate 15, and then the spring 13 is reset, thereby driving the second limit plate 15 to reset and clamp the first limit plate 14. When the user needs to disassemble, the user turns the handle 5 clockwise to move the second adjustment plate 9 downward to push the first limit plate 14, until the second limit plate 15 stops clamping the card plate 10, and then turns the handle 5 counterclockwise to drive the card plate 10 to leave the clamping slot 12, thereby completing the entire operation process.

[0037] The beneficial effects of the above embodiments are:

[0038] The dustproof structure of the sealing sleeve drives the screw to rotate by turning the handle, and the user sets a limit rod, a first adjustment plate, a second adjustment plate and a clamping plate, so that the first limit plate can be pushed by the first adjustment plate and the second adjustment plate, and the clamping plate can be clamped by the second limit plate, so that the first dustproof plate and the second dustproof plate can be connected to the wiring harness.
